If you set goals for yourself and you're like a lot of other people, you probably realize it's not that your goals are physically impossible that's keeping you from achieving them, it's that you lack the self-discipline to stick to them.
Si tienes tus ideales y eres como mucha gente, probablemente te das cuenta de que tus ideales no son físicamente inalcanzables lo que te impide lograrlos, sino que te falta autodisciplina para lograrlos.
